I have usually completed the Daily Telegraph Crossword and weekend Prize versions by 4:00am having received the newspaper electronically a couple of hours beforehand. Finding myself in the position to post the answers before most folk have woken to their hard copies, I am happy to oblige. However, how do I post answers to questions yet to be asked and how can I receive notification when someone is stuck? In other words, what is the most efficient technique you veterans adopt in answering questions?
